FPT not found

[simonepsp]

Hi,
I'm trying to deblob the intel ME image of my Thinkpad X230 but the script reports "FPT not found".
I checked with an hex editor and the issue seems related to the $FPT position. The script is looking for "$FPT"on 0x30 but on my Intel ME image it is located on 0x3010...

Fixing the seek to 0x3010 isn't enough 'cause even the FPTR partition is "wrongly" located and the script can't find it.
Thanks for your help

P.S. I'm sure that the dump is correct. I have already double-checked it. :)

Hi, I think you're using the full dump, me_cleaner doesn't support yet the full image Extract the image before with ifdtool -x, then use me_cleaner on the resulting me region

Thanks for pointing that out :)
Unfortunately I still have a problem with the checksum correction:

Correcting checksum...
Traceback (most recent call last):
File "me_cleaner.py", line 84, in
(sum(checksum_bytes) - checksum_bytes[0x1b]) &
TypeError: unsupported operand type(s) for +: 'int' and 'str'

Any ideas? Thanks

Try to replace checksum_bytes[0x1b] with unpack("<B", checksum_bytes[0x1b])[0]

[simonepsp]

same error. I think the issue regards "sum(checksum_bytes)". Probably because it can't sum() a string.

solved. The script must be run with python 3 to work.

Yes, as stated in the shebang
I'll add a notice in the README
Please add a comment in #3 if it works on your thinkpad
